T all whom it may concern:

Be itknown that we, AXDR W Rum, printer, and Jonx JAMESON, eonsultl ng engineer, both subjects of the Queen of Great Britain and Ireland, and both residing at Akenside Hill, Neweastleuponilyne, England,hareinvcuted certain new and useful Im provementsin Tmnsformation Pictures and Prints, (for which we have applied for patents in Great Britain, No. 1,380, dated Jzinnary 31, 183' and have obmined patents in France, dated March 7, 1885,

No. 167,490, and Belgium, dated April 24, 1885, No. 68,631,) of which the following is a specification.

Our invention consists in improvement in pictures and prints, so as that part: or 1*. picture or print shall he fixed to and part reniow able from the paper on which it, is placed, and is a new application ofthe process of protected cheque-printing patented liy John Jameson, in Great Britain on l-leccmher 27, 1583, No. 5,878.

In carrying out our invention we proceed as follows: \l'e print upon ordinary paper or card any convenient design, which we call the fixed design, and then coat? the whole or part of the paper so printed with such material as starch and gum, so as to form upon it. a soluble invisible, or scarcely visible, inedinm, and when this coating is dried we print upon it, in register with the print; of the fixed design, a superimposed design cit-her covering entirely the fixed print; or partially covering it, and forming with uncovered portions of the fixed design a complete picture. The effect of this arrangement is that if the print; is washed with a solvent of the film the design will he transformed by the removal and disappearance of all parts of the print w ii: 27'"; placed above the couch of soluble medium, and the fixed design only will appear. As an alternative, we may use for the first, printing ordinary pI-inting-ink,m1d for the second printing a soluble ink composed of such material as gum and glyccrine, or soap or alhuincn, and trcucle, with eolorlugniattcr ground up as an ink, so that on the solution of the soluble ink the trunsfornnition is cifccted; and it, is of course possihlc still further to vary the prooess by using over the. fixed print films or sol uul-L- inks, perhaps insoluble in water, but; soluble in other material, or to use one fixed ink with one ink or iilm soluble in water and another ink or film soluble, for instance, in spirit, but not in water.

Our invention is nppllcahle also to other printed matter as well as pictures, and the printing may be produced either in the ordinary printing-press or by the lithograph process, or otherwise, and may be ext-ended so that, more than one printing (as in chromo lithography) shullhe fixed and more than one printing shall he delehle.

\l'e purpose to use the invention for advertisements, and in CllIlSlillflS'C'ifl'dS, birthdaycnrds, in valentines, and similar matters, and as a source of amusenn-nt and instruction for children.

llnring thus described the nature of our invention, we will proceed more particularly to llt'SClllJ the manner in which the same is to he performed-that is to say:

Referring to the accompanying drawings, Figure I is a view representing the appearance ofu picture having the fixed design, coating on the fixed d esign,aud superimposed removahle design. Fig. It is a view showing the transformed appearance of the picture after the superimposed design has been washed off.

A is the paper or hacking; 3, the fixed design; (5, the coating. and l) the removable design.

In the process we prefer to use we make a solution of gum-arnliic in water so that; the density of it. is about 1.085 to 1100, water being 1.000, and we add to it a strong solution of starch in such proportions (which must vary with the quality of the starch) as thatwhen spread on paper A it shall dry without a disagreeable glaze. This we employ for th soluhle film C, before mentioned. Next, unless the paper he specially prepared in the mill, we wet the paper to he used for prlntingand allow it to dry again, so as to take out the stretch which paper gets usually in the mill, and we prefer to allow it to dry each sheeti'by itself, so that its contraction may be unhindered. When it is dry, we print; it; the first:

time, and when the print B has dried we coat the paper, either with a brush by hand or in a varnishing machine, with the film composition 0, before described, and again allow it to dry, 5 each sheet by itself. \Ve then press in con sidernhle quantity the sheets together, so as to make them tint and convenient for the second priut,D,nnd then npplyin r gister wi h "1e first the second printing in the ordinary way, and when this is dry, it there be several in a sheet, we cut into separate pictures. If the exact. register of the two prints is not: of much im portauce, we omit the first wetting of the paper, and we sometimes omit it if the picture is small and not many printed on the some sheet. The object of the first; wetting is to prevent the diilicu'lty of register from dist-oi tion of the sheets of paper by shrinkage in the drying ofthe film. \Vhen a soluble inlczis used for the second printing and no coating of film is applied, we omit the wetting of the paper. The thickness of coat. of film should vary with the absorptive power of the paper. A hard paper will require less and a soft paper more; and italso depends to some extent upon the depth otshnding, of the top print. it is impossible to lay down specific rules to suit the various circumstances, excepting that n. snilicient coating must be applied to prevent penetration of the ink of the top print.

Although we have described the mnterialoi' the soluble film which we ,"FL'fii' .2- use, we do not confine onrseves to that. nintcrinl, as other materials are if not equally good at least-nearly so. For instance, dextrine may be substituted for the gum, and ordinary paste may be substituted for both the starch and gum, and there are many other substances which may be used in the some manner. Although, also, we 40 have described the application of the film by 9. brush or varnishing machine and as if it. was over the whole of the paper, we sometimes costonly parts of the paper to be printed, and we may carry this out by the application of 45 the soluble film as a print. with a lightpressure from a soft-wood block, (such as a pear tree;) or we may print the soluble film from the wood block as last. described in the form of a more orless minute invisible design, and either before the first. printing of the paper or after, so that only the parts of the visible print which are over the invisible print are removed by springing.

It; will be clear thatnll printing in ordinary printing-ink over a sol nble film, and whether in one color or more, is delible, and all printing in ordinary printing-ink direct open the paper, whether in one color or more, is fixed to the usual extent.

\Ye. clnim- I 1. A transformation picture or print consisting of a backing having an indelible imprint thereon and n deleble print upon said imprint and backing concealing in whole or in part the imprint, substantially as described.

2. A transformation picture or print con sisting of an indeliliie imprint and two or more separate printings superimposed in films solnble in different media, so as on application of the solvents of the films to develop transformations, substant-ially as described.

3. A transformation picture or print consisting ofn hocking or sheet, a fixed design or imprint on the backing or sheet, and a removable design or printing concealing in whole 75, or in part the fixed design or imprint and :nlnptedto be p fished off without; destroying the latter.

4, A transformation picture or print consisting of a backing or sheet, a fixed design or imprint. on the hocking or sheet, a coating on said fixed design or imprint, and n removable design or printing over the tint-d design or imprint concealing the latter in whole or in part, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
